YApplication filed October 22, 1908. Serial N o. 459,000.

To all whom it may concern: Y

lBe it known that I, HENRY JONATHAN LAWRENCE, apcitizen of the United States, residing at Longbeach, in the county of Los Angeles and State of California, have invented a new and useful Wave-Motor, of which the following is a speciiication.

It is the obj ect of the present invention to provide a wave motor sov constructed as to be operated directly through the impact of the waves. c i

A further object of the invention is toprovide a wave motor including a wave impact member having an under surface presented waveward so that the impact of the waves will act to raise the member, meansbeing provided tending normally to lower4 the member. A

A still further object of the invention is to provlde, in a wave motor, a wave impact member which is mounted Vfor vertical oscillation and which has a convex under surface which is presented waveward.

Heretofore, in constructing .Wave motors, it has been customary to embody the wave impact member in an oscillatory platform the free edge of which is presented shoreward so that the member will rise andfall with the waves, but I have found that by mounting the wave impact member with the free edge presented waveward and likewise itsunder face, that a greater latitude of movement is provided for with the result that more work is performed by the motor. i In connection with such a wave impact member, kI providel some suitable means which tends to lower the member so that after impact of each Wave with the member, it is automatically, quickly, and with considerable force, swung downwardly.

f In the accompanying drawings, Figure V1 is a top plan view of the motor embodying my invention, and Fig. 2 is a vertical longitudinal sectional view therethrough showing the manner of arranging the same.

In the drawings, there is illustrated a shaft 5 which is supported between suitable bearings 6, the shaft being fixed in the bearings, and carried by the shaft in such'manner as to permit of oscillation are arms 7 which are preferably in the nature of beams, the connection of `the arms with the shaft being had by means of suitable clevices which are bolted to the inner end of the arms and embrace the shaft 5, it being understood that Specification of Letters Patent.

Patented April 20, 1909.

the bearings 6. of the shaft are located upon the bed of the river or ocean in which the motor is arranged.

rlhe ends of the arms which are connected to the shaft 5, are presented shoreward and their opposite or free ends are presented in a direction which for the sake of convenience in describing the invention, will be termed waveward. The under sides of thearms 7 are convexed and tapered in the direction of their free ends and secured to the under edges of the arms and connecting the same are a number of boards 9 which are placed edge to edge and extend in a continuous series from the free ends of the arms to a point inwardly of said ends, the location of this latter point being determined by the character of the body of water in which the motor is placed, or in other words by the wave force. As before stated, the `under sides or edges of the arms '7 are convexed and the arms are tapered in the direction of their free ends so that in securing the boards 9 to the arms, a convex -impact surface will be presented by the boards and the curvature of the surface is such that an incoming wave will strike n, against the under sides of the boards 9, orr in other words, against the convex wave impact surface which is presented by the boards, this surface being, as before stated,.presented waveward. A beam 10 is also connectedwith the shaft 5 in the same mannerl as are the arms 7 andthis beam extends in the same general direction as the armsand substantially midway between the same and above the boards 9, it being provided upon its under side with a spring 10 which acts as a buffer between the said beam 1 0 and the impact member. This beam 10 projects waveward beyond the free edge of the wave impact member just described and between a pair of uprights 1 l which are arranged beyond the said impact member and which are provided at their upper ends with a cap 12 supporting a pulley 13 and its bearings. An eye member 14 is secured to the beam 10 at the outer end thereof and suspended loosely from the eye member is a weight 15, therebeing a power transmitting cable 16 also connected with the eye member and trained over the pulley 13 in the direction of the shore. The weight 15 is preferably of such size that after the wave impact member and beam l0 have been oscillated or swung in an upward direction and the wave llt) has receded they will quickly and with considerable force swing downwardly thereby drawing in a ositive manner upon the cable 16. The cab e 16, as before stated, is eX tended shoreward and is there connected with any suitable power converting mechanism.

As before stated, one of the salient features of my invention'resides in so arranging the wave impact member that its under or impact surface will be presented waveward so that the impact of each wave will serve to elevate the member to the fullest possible extent thereby providing for a down stroke of longer duration than if the said surface was presented shoreward. preferably provide upon the impact member two or more barrels or casks 17 which add buoyancy to the said member.

For convenience in designating the elements in the claims the im )act member 9 and its su porting beam 7 will be termed the wave-osci lated impact member and the beam l0 will be designated the weight-controlled power member.

W'hat is claimed iszl. In a wave motor, a wave oscillated impact member, and a weight controlled power member.

2. I n a wave motor, a wave oscillated im pact member, a power member independent of the wave oscillated member, a weight supported by the said power member and tending to move the same in one direction of its movement, and a power transmission means connected with the said power member.

3. In a wave motor, a wave oscillated impact member, a power member, and a weight for imparting movement to the power member in one direction.

5. In a wave motor, a wave oscillated impact member, a power member', and a weight connected with the power member and tending to lower the same.

6. In a wave motor, a Wave oscillated member, a power member, a weight supported bey ond the power member and tending to lower it, and a power transmission means connected with the weight supporting means.
